LUBRICATOR.

Application filed April 6, 1905. Serial No. 254,136.

of New York, have invented a new and useful Improvement in Lubricators, of which the following is a specification.

This invention relates to that class of automatic journal or bearing lubricators compris- IO ing a reservoir or casing which incloses the bearing, a centrifugal disk mounted on the Shaft or other part to be lubricated and dipping with its lower portion into the oil in the reservoir, and a stationary feed device which 5 receives the oil thrown off by the disk and delivers the same to the shaft-bearing.

The object of my invention is to improve the construction of the stationary oil-feed device with a view of insuring a constant and oil to the bearing.

In the accompanying drawings, Figure 1 is a sectional elevation of ,a double eccentric or crank shaft and a pai-r of pitmen provided with the improvement. Fig. 2 is atransverse 5 vertical section in line 2 2, Fig. l. Fig. 3 is a horizontal section in line 3 3, Fig. 2.

' Similar letters of reference indicate corresponding parts throughout the several views. A indicatesa shaft, supported in a standard O A' and having double eccentrics or cranks t cl.,

and B B are pitmen having heads or bearings C of any ordinary construction which embrace the eccentrics or cranks ce.

D is the oil reservoir or casing inclosing 1,. 5 the pitman-heads and cranksand closed on all Sides except where the same has openings for the passage of the pitmen.

E indicates the centrifugal member, preferably consisting of a dished disk secured to O the shaft between the pitman-heads and dipping into the oil in the lower portion of the reservoir, so as to transfer a portion of the oil from the latter to the stationary feed member F. This feed member consists of a plate 'y 5 or fin arranged transversely in the reservoir closed top thereof, both pitman-heads The and depending from the the plate extending across in line with their oil-holes g, as shown.

lower edge of the feed-plate is notched or re- I cessed to receive the peripheral portion of the disk, as shown at f. The portions of the plate on opposite sides of the disk are V-shaped, and their points or apexes f coincide with the oil-holes g. By this construction the plate is provided above each pitman-head with inclined edges fzfz, which converge to the drippoints f', located directly over the corresponding oil-holes, causing the oil which is thrown against the feed-plate by the centrifugal disk to iiow down the side of the plate and then follow its inclined edges to said points, from which it falls in drops or small quantities into said oil-holes.

The V-shaped portions of the feed-plate preferably extend to within a short distance of the upper sides of the pitman-heads,` and the rotary disk is of sufficient diameter to extend nearly to the top of the oil-reservoir.

In the drawings the invention is shown in connection with two oppositely-acting pitmen, such as are employed in grain-separatorsfor vibrating screens in opposite directions; but the improvement is equally applicable to a single pitman-head, journal, or other Apart to be lubricated.

I claim as my invention- The combination of a shaft having a pair of eccentrics, pitmen-heads embracing the eccentrics and having oil-holes, a centrifugal transfer member mounted on the shaft between said heads, and a transverse feed-plate depending from the upper Side of the reservoir and provided in its lower edge with a THEODORE F.
